CAR-AXLE-BOX LID.

Specification of Letters Patent.

Patented Jan. '7, 1908.

Application filed February 16. 1906. Serial No. 301387.

To all whom it may concern:

Be it known that we, FREDERICK lIAoir- MANN, a citizen of the United States, and WALDEMAR EmoxsEN, a citizen of the Kingdom of' Denmark, both residing at Minnea olis, in the county et Hennepin and State oi Minnesota, have invented certain new and useful Improvements in Oar-Axle-Box Lids; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide an improved car axle box lid, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The improved device involves a supporting arm which is hinged or pivoted to the axle box, and a lid which is mounted on and carried by said supporting arm, and is connected thereto in such manner that when rotated or moved pivotally, it will move laterally with respect to the said arm to and from engagement with the lid seat and the said box.

As illustrated in the drawings and as hereinafter specificallyV described, provision is made whereby the said arm will be locked to the box in a position to hold the lid in a closed position, and the lid is arranged to interlock with the box when seated against the same, in such manner that the said supporting arm is in turn locked in the supporting position stated.

Two forms of the improved device are illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views. l

Referring tothe drawings: Figure 1 is a view in front elevation, showing a car axle box having applied thereto an improved journal box lid designed in accordance with our invention. Fig. 2 is a side elevation ol box being broken away. Fig. 3 is a view corresponding to Fig. 2, but showing the lid in an open position, some parts ol the box and lid being broken away. Fig. 4 is a vertical section taken on the line fr of Fig. 1, some parts being broken away. Fig. 5 is a detail in plan view, showing the hinge bolt which pivotally connects the lid-supporting arm to the axle box. Fig. G is a view corresponding to Fig. 1, but illustrating a modiiied construction. Fig. 7 is a section taken on the line w? a, of F 6, some parts being broken away. Fig. 8 is a view in side elevation, seme parts being broken away and some being sectioned, olE the parts shown in Fig. 6. Fig. 9 is a detail view in plan, illustrating a modified construction ol'- the lid hinge bolt, and Fig. 10 is a detail view in side elevation, showing a lorm of hinge lug used in connection with the bolt shown in Fig. 9.

Attention is 'lrst directed to the construction illustrated in Figs. 1 to 5, inclusive. T he axle box l is olz the usual construction, except that in its open outer face it is formed with an annular Vllange 2 that a'llords a seat 'lier the axle bex lid 3. 'lhis axle box lid 3 is el disk-like l["orm, and, on its outer face, is formed with an annular groove that receives and closely `lits the annular rim or seat of the box. The axle bex 1 is provided udth a heavy hinge lug l, in which is rigidly secured the hinge bolt 5, the projecting ends of which are Ilattened at 6, thereby all'ording an angular trunnion-like projection at each side of said bolt. The hinge bolt 5 is rigidlyT secured in the lug 4, by means of a set screw 7, but it may be otherwise secured, and the angular trunnion may be otherwise formed. The lid 3 has a screw-tlneaded center hub portion that werks on a threaded stud S, formed at or rigidly secured to the lree end of a lidsupporting arm 9. This lid-supporting arm 9 is bilurcated, and in the upper ends of its prongs seats 10 are formed, that adapt the lid-supporting arm 9 to move pivotally upon the angular trunnions 6. The seats 10 ,are formed with angular extensions 10l and 10b that extend at an angle of about 90 degrees to each other. The numeral 11 indicates a coiled spring that surrounds the threaded stud 8 to the arm 9, and is attached at one end to said arm 9, and at its other end to the lid 3. The tension oi the spring 11 is such that it tends to rotate the lid 3 on the stud 8, in a direction to move the said lid away 'lrom the arm 9 and against its annular seat 2 on the box.

The relative arrangement of the parts described is such that when the lid-supporting arm 9 is turned pivotally downward and then moved so as to carry the seat extensions 10at onto the angular trunnions 6, said arm will be locked against rotation and will hold the lid 3 in position with engagement with its seat 2 on the box. The said arm when thus interlocked with the fixed angular trunnions 6 ofl'ers a base of action for the lid 3, and the lid then being allowed to turn underthe tension of the spring 1 1 or being otherwise turned in the direction of the arrow marked on Fig. l, will be moved into engagement with the seat 2 on the box, and the annular groove on its inner face, when pressed onto the said seat 2, will interlock the lid to the box in such manner that the arm 9 cannot be moved out of interlocking engagement with the fixed trunnions 6. The lid is then securely interlocked in its closed engagement with its seat on the box, and the box is tightly closed in such manner that oil cannot escape from the box, and dust or dirt cannot enter into the box.

To move the lid into an open position, it is first necessary to rotate the same on the threaded stud 8 and against the tension of the spring 11, in a proper direction to carry the lid toward the arm 9,A and far enough away from the annular seat 2, to permit the lid to move upward clear of the said seat 2.

Vhen this is done the arm 9, together with the lid, may be moved upward far enough to carry the seats 10 into line with the fixed angular trunnions 6, and this being done the arm 9 may be moved pivotally upward together with the lid, approximately into position shown in Fig. 3, and then by engaging the seat extensions 10b with the fixed trunnions 6, the said arm 9 will be interlocked to the box, as shown in Fig. 3, and the lid will be securely held in open position.

The spring 11 may of course be dispensed with, but is desirable because it serves to hold the lid in a closed position tightly against the box, and prevents the same from being jarred or otherwise accidentally opened or unseated.

The construction illustrated in Figs. 6, 7 and 8 is like that already described, except as hereinafter noted. 1n this construction the supporting arm 9', at its free end, instead of having a threaded stud as previously d escribed, is formed with diametrically projecting cam blades 12, the peripheral ends or ortions of which extend at an angle to the face of the lid so that they act as segmental threads. These cam blades or segmental threads work in correspondingly formed cam seats 13 in segmental lug-like projections 14, that are cast integral with or otherwise rigidly secured to the outer face of the lid 3a. The cam blades 12 and their cam seats 13 act very much like the screw-threaded stud and hub of the previously described construction,

but operate to move the lid. into and out of engagement with the seat on its box more rapidly, or, in other words, under a much less rotary movement of the lid. Considerably less than 45 degrees of rotary movement of the lid, with respect to the supporting arm 9, will with this latter described connection serve to move the lid from its seated position into a position to clear the box, or vice versa.

'To prevent accidental unseating of the lid under jar incident to the service, the seat lid is shown as provided with an over-poising weight 15 in the form of a heavy lug cast on the inner face thereof. Also, in this construction the lid-supporting arm 9 is extended downward, and is terminated in a lock lug 9a that engages with the coperating lock lug la on the box 1, to hold said lid in -a closed osition. -This interlocking engagement ofD the 'lower end of the arm 9 and the box relieves the pivotal connection of the arm to the box from strains, and permits the said arm and the saidvpivotal connection to be made much lighter than would otherwise be practicable, and, furthermore, makes it possible to eliminate the interlocking pivotal connection, although this latter is desirable in order to hold the lid in an open osition. ln both of the constructions above escribed the lid is shown as provided with several marginal lugs 16, that are adapted to be struck with a hammer or taken hold. of by the hand, to impart an initial rotary movement to the lid necessary to unseat the same from the box. v

In Fig. 9 we have shown a hinge bolt 5a, having a flattened central portion 6a. In Fig. 1() the bolt seat 10 in the hinge lug 4a of the box is provided with angular extensions 10c and 10d, for engagement with the flattened central portion 6a of the bolt 5a. With this construction the ends of the hinge bolt 5a should be rigidly secured to the prongs of the arm 9', and the flattened cen-v and hold the arm and lid in a raised position corresponding to the position shown in Fig. 3.

The lid above described and associated devices for supporting the same, are of comparatively .small cost, are strong and durable and eflicient for the purposes had in view. The lid may be very quickly and easily opened and closed and when closed tightly closes the box.

We claim as our invention:

1. The combination with an axle box and a lid, of a lid supporting arm connected to said box by an interlocking pivotal joint, and the said lid being connected to said arm with freedom for lateral movements with respect thereto to and from a seated position on the box, when said arm is interlocked to the said box, substantially as described.

2. The combination with an axle box having an annular lid seat, of a lid-supporting arm connected to said box by an interlocking' joint, and a lid having a threaded orspiral engagement with said arm, whereby said lid may be rotated and moved laterally toward and from said arm to and lrom a seated position on said box, substantially as described.
